A sixth person has been charged with terror offences over the Paris terror attacks.
A judge in Belgium charged the man with terrorist murders and participation in the activities of a terrorist organisation, according to reports.
"Yesterday a person has been arrested in Brussels for interrogation," the federal prosecutor said in a statement quoted by AFP news agency.
"The investigating judge has remanded him in custody and charged him with terrorist murders and participation in the activities of a terrorist organisation."
Two other people, said to be the brother and father of the man who was charged, have been released, according to the Reuters Trust.
Police raids linked to the Paris terror attacks have taken place in Belgium, where a number of the terror suspects were based.
Sixteen people were arrested in a day of raids around the capital Brussels last Sunday, one of whom was charged and a further 15 released.
However, key suspect Salah Abdeslam, who lived in Brussels, is still being sought by police.
France has today been remembering the 130 victims from the wave of coordinated terror attacks, including the Briton Nick Alexander.
